Here's a general guide. Specifics may vary slightly depending on the engine type (e.g., V6 or V8). Consult a repair manual specific to your Monte Carlo's engine for precise details and diagrams.
Tools You'll Need:
* New fan belt: Make sure to get the correct size and type. The belt's length and profile are crucial. Check your owner's manual or an auto parts store for the correct part number.
* Wrench(es): You'll likely need various sizes depending on the tensioner and alternator bolts.
* Socket set: Helpful for accessing difficult-to-reach bolts.
* Screwdrivers: Possibly needed depending on the type of tensioner.
* Gloves: To protect your hands.
* Jack and jack stands (highly recommended): Lifting the car will make access much easier and safer.
* Repair manual: Specific to your '86 Monte Carlo's engine is invaluable.
Steps:
1. Preparation: Disconnect the negative battery terminal. Locate the fan belt. It typically runs around the crankshaft pulley, water pump pulley, alternator pulley, and possibly others.
2. Accessing the Belt: This often requires getting beneath the car. Use jack stands and follow proper safety procedures for lifting the vehicle.
3. Tensioner Release: This is the most critical step. There's usually a tensioner pulley that allows you to loosen the belt. This could be a spring-loaded tensioner that you need to push or turn with a wrench or a ratchet. Your repair manual will show you how this works on your specific engine. This is where you'll likely need the wrenches and/or sockets. The goal is to create enough slack in the belt so you can easily slip it off the pulleys.
4. Removing the Old Belt: Once the tension is released, carefully work the belt off the pulleys. Start by releasing it from the largest pulley first.
5. Installing the New Belt: Route the new belt around the pulleys in the same path as the old belt. Make sure it sits correctly in the grooves of each pulley.
6. Releasing Tensioner: Once the belt is routed correctly, release the tensioner, allowing the tensioner to automatically re-engage and tighten the new belt. Ensure the belt is seated correctly on all pulleys.
7. Checking Tension: Manually check the belt tension. There should be a small amount of give, but not too much. Consult your repair manual for proper tension specifications. If the tension is too tight or too loose, readjust it.
8. Reassembly: Carefully lower the car from the jack stands.
9. Reconnecting Battery: Reconnect the negative battery terminal.
10. Testing: Start the engine and listen for any squealing or unusual noises. Check that the belt is running smoothly on all pulleys.
Important Considerations:
* Tensioner Type: Different Monte Carlos might have different tensioner mechanisms (automatic or manual). The repair manual will be crucial here.
* Pulley Alignment: Ensure all pulleys are aligned correctly before installing the belt. Misalignment can cause premature belt wear and damage.
* Belt Routing: Get the routing absolutely correct; incorrect routing can lead to belt slippage or damage. Your repair manual will have a diagram.
Disclaimer: This is a general guide. Improper repair can cause serious damage to your vehicle or injury to yourself. If you are not comfortable performing this repair, take your Monte Carlo to a qualified mechanic. Using a repair manual specific to your vehicle is strongly recommended.
